2. A fastener socket including a resilient ringlike stud-engaging part, an attaching part loeated at the opposite side of a socketearrying medium, and a plurality of attaching prongs presented by said ringlike part, said prongs being yieldable laterally with said ringlilie part, said prongs having their end portions Jassing throngh the carrying inediuni and bent downwardly by and into engagement with said attaching part to secure said parts to the carrying rnediun'i, said downwardly'bent portions adapted to swing as on a pivot within said attaching part thereby to permit tree expansion of said ringlike part without interi'eience from said prongs dnringvengageinent or disengagement of said ringlike part with astrid.

3. A socket for a separable fastener including a resilient ring-'like stud-engaging part, expansible and eontractible as a whole, a cap ineniber located at the opposite side of a Ytiexible socket-carrying niedinin having a gene ally curved prong-delecting wall, and a plurality of attaching prongs .lorined integral with said ringlike part, said prongs passing through a support for said socket and bent; downwardly by the vall ot said eap to Contorni relatively closely to the curve ot said wall, the ends ot said curved portions of said prongs adapted to shi'tt diagonally downwardly with relation to said curved wall dining expansion of said ringlilie stndengaging part thereby to perinit the nnenried portions ol' said prongs to yield with said ringlilie part.
